Rose plant named ‘ESM R107’

ABSTRACT

A new and distinct cultivar of Rose plant named ‘ESM R107’, characterized by its upright, long and strong flowering stems; vigorous growth habit and high productivity; dark green-colored leaves; peach pink-colored flowers that are held on strong pedicels on relatively large sprays; freely flowering habit; and excellent postproduction longevity.

Botanical designation: Rosa hybrida.

Cultivar denomination: ‘ESM R107’.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Roseplant, botanically known as Rosa hybrida, commercially used as a cutflower Rose plant, and hereinafter referred to by the name ‘ESM R107’.

The new Rose plant is a product of a planned breeding program conductedby the Inventor in El Quinche, Pichincha, Ecuador. The objective of thebreeding program was to develop new cut flower Rose varieties withattractive flowers and excellent postproduction longevity.

The new Rose plant originated from a cross-pollination made by theInventor in November, 2008 of a proprietary Rose selection identified asLine 188, not patented, as the female, or seed, parent with aproprietary Rose selection identified as Line 222, not patented, as themale, or pollen, parent. The new Rose plant was discovered and selectedby the Inventor as a single flowering plant within the progeny of thestated cross-pollination in a controlled greenhouse environment in ElQuinche, Pichincha, Ecuador in September, 2009.

Asexual reproduction of the new Rose plant by bud grafting in ElQuinche, Pichincha, Ecuador since March, 2010 has shown that the uniquefeatures of this new Rose plant are stable and reproduced true to typein successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

Plants of the new Rose have not been observed under all possiblecombinations of environmental conditions and cultural practices. Thephenotype may vary somewhat with variations in environmental conditionssuch as temperature and light intensity, without however, any variancein genotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘ESM R107’. These characteristics incombination distinguish ‘ESM R107’ as a new and distinct Rose plant:

-   -   1. Upright, long and strong flowering stems.    -   2. Vigorous growth habit and high productivity.    -   3. Dark green-colored leaves.    -   4. Peach pink-colored flowers that are held on strong pedicels        on relatively large sprays.    -   5. Freely flowering habit with typically about seven to nine        flowers per spray.    -   6. Excellent postproduction longevity.

Plants of the new Rose differ from plants of the female parent selectionin the following characteristics:

-   -   1. Plants of the new Rose have longer flowering stems than        plants of female parent selection.    -   2. Stems of plants of the new Rose have fewer thorns than stems        of plants of the female parent selection.    -   3. Flowers of plants of the new Rose have more petals than        flowers of plants of the female parent selection.    -   4. Plants of the new Rose and the female parent selection differ        in flower color as plants of the female parent selection have        orange-colored flowers.

Plants of the new Rose differ from plants of the male parent selectionin the following characteristics:

-   -   1. Plants of the new Rose are slightly smaller than plants of        the male parent selection.    -   2. Plants of the new Rose and the male parent selection differ        in flower color as plants of the male parent selection have        orange-colored flowers.

Plants of the new Rose can be compared to plants of Rosa hybrida ‘EsmDurazno’, disclosed in U.S. Plant Pat. No. 21,004. In side-by-sidecomparisons conducted in El Quinche, Pichincha, Ecuador, plants of thenew Rose differed from plants of ‘Esm Durazno’ in the followingcharacteristics:

-   -   1. Plants of the new Rose were larger than plants of ‘Esm        Durazno’.    -   2. Plants of the new Rose were more vigorous than plants of ‘Esm        Durazno’.    -   3. Plants of the new Rose were more freely branching than plants        of ‘Esm Durazno’.    -   4. Plants of the new Rose had larger leaves and leaflets than        plants of ‘Esm Durazno’.    -   5. Plants of the new Rose had larger sprays with more flowers        per spray than plants of ‘Esm Durazno’.    -   6. Plants of the new Rose and ‘Esm Durazno’ differed in flower        color as plants of ‘Esm Durazno’ had light salmon pink-colored        flowers.    -   7. Plants of the new Rose had longer pedicels than plants of        ‘Esm Durazno’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs, following observations and measurementsdescribe plants grown in 10-liter containers in a polyethylene-coveredgreenhouse in El Quinche, Pichincha, Ecuador and under typicalhydroponic Rose production practices. Plants were pinched 13 to 14 weeksafter planting and were two years and 23 weeks old when the descriptionand photographs were taken. During the production of the plants, daytemperatures ranged from 16° C. to 30° C., night temperatures rangedfrom 12° C. to 16° C. and light levels ranged from 800 to 1,200foot-candles.
